To all whom it may concern:

Be it 'knownthat RICHARD H. CARR, a cit-j. izen of the United States,residing at Colum bus, in the county of Franklin and State "of Ohio,has'invented certain new and useful,

Improvements in Outlet Structures for 'Oil the following is 1?,-

of imparting extended service with but a min'mum of repair andreplacement of parts.

*I the 'o eration of tank cars, considerable difliculty as beenencountered in rovidvalve or causing the latter to leak and "to.

ing a valve capable of preventing eakage of: the contents of the cars.This has been due to manycauses, some of-whlch may be attributed towater collecting in andaround the parts of the valve and then freezing,thereby fracturing fragileportions of'the become. generallyinefficient;- again, it is imperative that a close" seating valve -beprovided' and oneof positive operation in order to prevent'undue fluidseepage through the 1 valve, and finally careless operation of thevalves is a frequent cause'for undue loss of A the fluid containedwithin the cars.

' Therefore, the present invention has for and others,'- and wherein themechanism is of such construction as to provide a valve capable offirmly and positively seating, and j :ture A com rising the I presentinvention.

@ principles of the inventionandthe ada tan a tion .of the latterv aresoadmirably c car is formed with an. opening 2 inwhi'ch isvertically,mounted the improved valve struc-- Concentrica y surrounding theopening2 is 'a collar 3, which is riveted or otherwise tank 1;- Arranged to besecured to this collar isa valve cage 5, this latter being 'disdverticallywithin the tank and has its ower and formed to provide anoutturned flan 6 whichis disposed to lie-contiguous to t e collar 3. Asshown in Figure 1, the

seemed as at 4 to the lower portionof the I taining bolts 7. As shown,these bolts have their upper ends threaded into openings provided in thecollar 3, andysaid bolts are further formed with flanges 8 which are arranged toengage with the under surfaces of, the flange 6'. Obviously, bythreadlng the bolts*7 into-the openings provided therefor arrange in thecollar 3, sald bolts will be positioned so that their flan es 8 willbind the flange 6 of the cage mem er 'injsecure'd relationship with thecollar 3. The casing of, the valve further comprises .an' exteriorconduit 9 which is formed from any suitable material and i of hollowcylindrical construction .i

The upper end of the conduit terminates in the outwardly extending,flange 10, which is ada ted to lie. in engagement with and imme iatelbelow the flan e 6. Bolts 11 are d to pass throng registering openingsformed in the cooperative flanges 6 and 10 and are threaded intoopenings provided in the bottom of the collar 3, whereby by virtue. ofthis construction the said bolts 11 will operate to securely bind andconnect the conduit in association with the cage and collar members. Inconjunction with the bolts 11, the conduit 9 is further supported byextending the shanks of the bolts the cage member and yet the latterwill be retained in secured connection with the collar 3. Thus, in theevent of injury to the exterior conduit, substitution of parts may be.quickly and easily efl'ected without disturbing the interior parts.

The cage member 5 is of hollow construction and as before stated extendsupwardly within the tank 1, the lower end of said cage bein providedwith a plurality of fluid openings 13 and also with a removable threadedvalve seat 14. The upper end of the ca e is threaded as at 15 to receivea cap 7 extension 16. This extension is provided with an axial opening17, in which is slidably mounted the stem 18 of a secondary valve 19.This valve is provided at its lower end with an inverted funnel shapedportion 20 which is normally disposed to .rest upon the valve seat 14, aspring 21 being positioned between the upper endof' the cap extension 16and the annular shoulder 22 provided upon the stem 18, said springnormally acting to maintain the portion 20 of the valve 19 in engagementwith the seat 14, the spring 21 exerting a pressure, of. substantiallyone. hundred pounds upon the valve to'maintain the latter in its seatedposition.

The stem 18 is of substantially hollow construction and provides aninternal cavity 23 in which is slidably mounted the stem 24 of a mainvalve 25, the latterbeing so disposed as to normally engage with theseat 14, substantially after the manner'shown in Figure 1. -A t coilspring or its equivalent 26 is situated between the reduced end of thefunnel shaped portion 20 of the secondary valve and the u persurface ofthe main valve 25, whereby through the instrumentality of the spring.26, the main valve will be pressed into engagement with the seat 14 atsubstantially a pressure of fifty pounds when the valve isrseated. Thusthrough the construction described it will be manifest that the outletport 27 formed in the seat member 14 will be normally closed by the mainand supplemental valves, and that the latter will positively operateunder the influence of 7 spring pressure to maintain the port 27 c oseagainst the effects of undue fluid seepage. The upper end of the valvestem 24 is bifurcated as at 25 and is provided with a transverselylocated cross pin 26', the secondary valve stem 18 is provided, in turn,with a cross pin 27' located at right angles to the pin -26 Normally,the pin 27 is positioned at an appreciable distance-beneath the pin 26'and, in view of thefact that the mechanism for opening the valve isdirectly connected with the stem 18, it will be apparent that thesecondary valve will be of the main opened prior to the openm valve,since, the secondary va ve may be elevated a considerable distance toeffect its opening before the pin.27 thereof contacts with the pin 26carried by the main valve. It will be noted that by virtue of thisconstruction and correlation of the cage and valve construction,freezing of water in any part of the construction can impart no damageto the valve.

The conduit 9 has its lower end provided with threads 28 upon which isthreadedly mounted a removable closure 29. This closure is attached bymeans of a chain'30 to a permanent portion 31 of the tank, a featurewhich permits the .closure to be operated frequently without becominglost or accidentally misplaced. When the valves '19 and 25 are opened,the closure 29 is removed 7 and the fluid contained within the tank 1may be permitted to pass ofl. Preferably, the closure is rovided with anapertured ear 32 through w ich a suitable form of seal 33 is passed,said seal being also attached to an -.,ear 34 formed upon the lower endof the conduit 9. By the provision of the seal 33,

surreptitious actuationof the valve may be readily denoted. Itfrequently occurs that water will collect within the conduit 9, and

to prevent this water when frozen from harming the construction, saidconduit is ,provided with-an upstanding i e 35. This pipe is adapted tobe forme mm a substantially-flexible material such, for example, asrubberor lead :'and is normally positioned, so as "to extend upright-==within the conduit." Thus, incase of water freezing in' the outletconduit, the pipe 35 collapses or is partially flattened before thepremure, due to the freezing, permits the cracking of the wall from theconduit 9. The lower end of the pipe is connected with a plug 36 whichis removabl threaded within the lower'portion of t e closure '29.-By-theuse of this construction, the pipe 35 may-be quickly andreadilyrenewed or replaced in its operative position within-the closure.Again, it will be noted that the upper end of the con duit 9 contiguousto the flange 10 is provided with a groove .37. By the provision of thisgroove the strength of'thewall'of the conduit is somewhat reduced atthis-point,

whereby in'the' event ofthe engagement of the conduit with an extraneousobject, the

conduit itself only will be broken and the.

damage therefore will not be transmitted to the interior valve mechanismof the tank.

" The operating mechanism for the valve isso formed'as to comprise avertically movable rod 38 which has its lowerend threaded as at 39 toreceive ayoke 40, the latter being permanently retained in its applied.position upon the lower end of the rod b #5 means of a lock nut41." Theyoke itself, is

provided with a cross pin 42Q-which passes through a venturi shapedopening 43 valve stem 18.-

rovided in the u per. end of the seconrihry virtue of this connection itwill be observ a substantially universal connection with the upperend ofthe stem 18. .The upper end of the rod 38 is provided with .a sphericalhead r 44 which-is positioned in "correlation withan elongated slot 45rovided in a ivoted actu-1 ating lever 46. his leveris substantially Lshaped formation and has its inner horizontal end pivoted horizontallywithin the spaced cars 47 of a link 48-, the link, in turn, beingpivotally connected with a vertical pivot 49 carried by a bracket 50stationarily mounted in any suitable manner within the dome 51 of thetank 1. The ver tical leg 52 of the lever is, as shown in dotted linesin Figure 6, normally positioned to en-I gage with a stirrup 53 mountedon the under side of the domewall 54. This is ac- I complishedbbendingthe upper end of the v leg 52 latera ly to provide an extension55 and then by terminating this extension in a downwardly extendingledge 56*,the extension 55 norma'lly'lying between the vertical legs ofthe stirrup 53 and is prevented from moving laterally by reason of theledge 56. When positioned in engagement; with the stirrup 53, the lever46 will positioned valve, it will that the rod 38 will have to permitthe main and secondary valves to be retained in closed engagement withthe.

valve seat 14. However, to open the valves, the hand is inserted throughthe inlet opening 57 provided in the dome 51 so that the vertical leg'52 of the lever-may be grasped said lever may be elevated to assume thefull line position shown in Figure 4. This permlts the rod 38 to beelevated, thereby opening the secondary and main valves in the mannerheretofore desc'ribed. The levermay be maintained inits elevatedposition by simply dropping its lateral extension over the upper edge ofthe opening 57 whereby the contents of the car may be drained.

It will-be observed thatothe slot 45 permits of the raising of the lever46, and also that the pivoted connection between lthe lower :end of therod and the upper end of the stem permits of the movement on the part-18 also ver 46 without undue binding action. --As shown in Fi ures, 5and 6, the

lever engages with the sldes of the opening 57 when the valve is opened.Thus, in the event of the operator forgetting to close the e impossibleto put the dome cover in place, since the vertical leg of the leveroflers an obstruction to this operation.- This feature prevents theoperator from forgetting the positions of the valve.

. In view of the foregoingdescription taken in conjunction with theaccompan ing draw 4 ings, it will be apparent that va ve' mechanism hasbeen provided ofan eiiicient character for the purpose set forth. By itsconstruction freezing within and around the valve will impart .no injurythereto, and the construction also serves to permit the valves to bereadily o ned and closed in a positive manner regar less of accumulativeice deposit. By virtue of the'fiared-lower portion 20 of the secondaryvalve, itwill be apparent that its contraction ,thereabout, will causesuch ice to' sli -upwardly away from the seat 14, thus a owing thelatter to be freely opened at alltimes. The double valveconstructionprovides extra seating area and,

hence serves to reduce fluid seepage to a minimum. Further, by theprovision of the reinforced rin construction 3 contortion in thewallsof-t e tank car. will not affect the valve structure or causethelatter to become faulty and liable to leak. It will be'apparent that bythe provision of the boltconstruction 7 and 11, the outlet conduit maybe readily removed from the car without disturbing the internal valvestructure. vBy removing the outlet conduit the valve seat 14 may besimilarly removed, and thus its seat may be ground in a simple and readymanwithin the confines of the lower enlarged end i her without causingthe operator to enter the of said secondary valve, said main valvebetank and to grind the valve seat while opering provided with a stemslidably disposed ating within the tank. The operating. mech-,withmtthe; hollow stem of the secondary 60 6 anism also permits thevalve to be readily valve, a spring positioned between said secopenedfrom a position of'advantage and .ondary valve and said main valve andoperserves to maintain the valve in its upright atingto maintain thelatter in engagement:
